GAOTek provides spectrum analyzers that monitor the levels of spurious signals, such as intermodulation products, noise, harmonics and other signals. The monitors will indicate the required levels by displaying the frequency of the signals on the horizontal scale and the amplitude of signals on the vertical scale. GAOTek sells spectrum analyzers to the United States, Canada and globally.
